Tracers are a bit different technology than servo control. We used two
true-trace tracer units in production for years.

I have one available for sale, by the way.

I seen a special on Pro Baseball bat manufacture. Each player provides his
favorite blank. They are numbered and stored. A hydraulic tracer lathe
turns the bats with the master in the tracer.
